How we test

Overall score includes:

Accuracy (80%)Ease of use (20%)

To check the monitors’ accuracy we took readings from a group of 10 men and women of varying ages. We then compared the results with those obtained from a recently calibrated hospital-grade blood pressure monitor.

Ease of use is assessed on the instructions, how easy the monitors were to operate, screen quality, the information displayed, and how comfortable the cuff was.
